OK. So...the backlight on the clock/radio multifunction display had two blown bulbs. So I bought 3 new ones. 1.2 watt...12v. All good so far.
I replaced all three. Now none of them work. The display still shows the time and date....but it has no back light. I have checked both f4 and f15 fuses. Both not blown. Everything else in the car is fine. I used a meter to check the bulbs were houses correctly in the holders. Thanks in advance

Did you put the bulbs in when the power was on? I found that blows bulbs.

Is it possible you've broken the track connector to the bulbs? The soldering is very flimsy, and is a Common problem with the MFD.
I've got a PPT30 that's open and I can show you what I mean.

Will I would say that you didn't fit the bulb holder in it's correct position to make a good contact with the circuit board.

It is none of the above things. Sorry so long to reply. I didn't get notification of replies. All soldering is fine....as tested with a meter for continuity. I also connected the bare bulb board directly to a 12v supply in my workshop. The bulbs all lit up. So..the bulbs are connected correctly.
